My brother has a son who is playing high school baseball. One of the things the coach suggests to him is to build up his forearms using long rice grains in a bucket. I looked at youtube and found a few videos of what people are doing with this and even with a powerlifter. My brother told me he did it and he felt it all the way up to his elbow and he thought it was better than using any gripper. I haven never read this on any discussion boards or any strength training articles. He also told me that many baseball players use it as well.
Is it really a gimmick or is there truth to this?
